fix(FEC-11542): tooltips in full screen don't pop out when hovering o…

…ver it (#4250)

**the issue:**
when in fullscreen, tooltips of bottom bar buttons are not displayed.

**solution:**
increase z-index of tooltips to 9999, as player ins fullscreen is having z-index=9999.
also had to delay the focus of play/pause btn when entering fullscreen, to prevent from the tooltip to appear in a wrong place.
